- •
Low cycle fatigue properties of CLAM steel were investigated at 450 °C and 550 °C.
- •
CLAM steel showed the continuous softening up to fail failure under cyclic loading. The degree of softening increased with increasing temperature.
- •
Dislocation density decrease and subgrain coarsening during the test process were the possible reasons for the cyclic softening of the CLAM steel.
